Lets keep the 'vdd_xx_abc labels' though which are used as input
supply pads for peripherals, for e.g.:
&usb_1_hsphy {
status = "okay";
vdda-pll-supply = <&vdd_usb_hs_core>;
vdda33-supply = <&vdda_usb_hs_3p1>;
vdda18-supply = <&vdda_usb_hs_1p8>;
};
IMO, here it makes sense to retain labels 'vdda_usb_hs_3p1' and
'vdda_usb_hs_1p8' in the dts (also making it easier to trace the same
in schematics).
I will send the v2 with the other suggested changes shortly.
